Used to show your pissed off about something but you don't want to raise the level of anger around you, so you make them laugh with a real random statement.
Person A: "Our history project is due after the weekend."
Girlfriend 1 - "Valentines day is coming up and I can't wait to see what I'll get this year."
Girlfriend 2 - "I've told my husband Valentines day is special and I don't want no 'club card flowers'. He'd better spend the time to go to a florist and send me premium flowers!"
